Sefer M.

✅ TOP RATED embedded systems developer specialized in firmware development for BLE devices based on Nordic nRF5x SoC. Extensive experience working with wide range of platforms (including, but not limited to: Nordic nRF51, nRF52, nRF53, nRF9160, STM32Fxxx, STM32Lxxx and STM8 series, Espressif ESP32 and ESP8266), as well as a variety of different peripherals such as sensors (motion, orientation, magnetism, infrared, capacitive, proximity, temperature, humidity, color, light etc.), displays, cameras, EEPROM and RAM memory chips, SD cards, 3G, 4G modems, GPS receivers and RF transceivers. ✅ Bluetooth Low Energy expert, extremely familiar with nRF51/nRF52 SoCs, which have been my main focus over the past couple of years. Deep knowledge of these chipsets, along with BLE protocol in general, allows me to efficiently design and develop fully functioning firmware ensuring highest performance with minimized power consumption. Whether it’s a simple gadget or more complex IoT system, when it comes to BLE, I’m THE guy. Furthermore, I wrote my master’s thesis on BLE mesh protocol, also utilizing nRF52. Contact me with some information about your project and let’s discuss how I can help YOU bring your idea to life. I’m always open to new opportunities and ready to take on any challenge you throw at me.
